Well, as part of an emergency response team - we have studied many crashes. Therefore you can reason this out as follows.
Unless you are seated in the cockpit or forward F/A jumpseat - I would not sit in front of the wings unlees my insurance was paid up. In a serious disaster, this group will not make it.
Over wing seating/exit rows. Exit seating was designed for emergency evac. In the event of a crash, the distortion of the structure from impact will probably make it impossible to remove the window exit anyway. Typically, the a/c will break away in front of the wing, behind the wing or both. Since you are seated on top a fuel tank, if it has not already combusted it will have been breached from impact and could very possibly be ignited as a result of the a/c breaking up. You will probably be engulfed in flames or quickly (seconds) be overcome by toxic fumes. I would not select these seats.
I do agree with the last row of the aircraft. If the planes dives nose first - the tail will break away. If you have a level impact - the tail will break away.
If you lose power and impact tail first - the tail will act as a fulcrum point and slam the rest of the aircraft into the ground and break away. You must remember that after you assume the crash position, you must remember to stay in that position for a minute after everything comes to a halt. DO
NOT LOOK UP
- as a result of the impact, there could possibly be a fireball the will surge through the cabin or down the aisle. Wait, if there is one you will hear it coming. Remember, most likely your exit is behind you. You must be familiar with your a/c briefing card as to how to operate the doors at your exit and/or blow the tail cone. MEMORIZE this. You must be able to close your eyes and visualize the demonstration pictures - YOU WILL BE
OPENING THE DOOR IN
DARKNESS more than likely due to spoke. Always crawl as low as you can. The smoke is HIGHLY TOXIC. Believe it or not, I always travel with a bottle of water that I place inside the seat back pocket in front of me in the event I need to wet my shirt to wrap around my mouth to breath. It will buy you those critical few seconds you will need. Also remember that sitting in the back row - all aircraft seats break forward - in your in the back row, you will not have anyone on top of you or anyone that hits you and adds to a secondary impact for you from behind.
If electric lines are involved you may not know. Try to exit the aircraft without touching the aircraft and the ground at the same time. Jump if this can be done without causing additional injury.
I hope this helps. I still believe flying is the safest way to travel. I firmly believe that those who are educated and fully prepared can and will survive a disaster. The briefing cards in your seat back pocket are an invaluable source of survival information.
Just as with everything else in life. Skiing, driving, swimming etc. - be educated, be prepared and never be indifferent.
